Kinetic Voronoi Diagrams and Delaunay Triangulations under Polygonal Distance Functions
Let P be a set of n points and Q a convex k-gon in R2. We analyze in detail the topological (or discrete) changes in the structure of the Voronoi diagram and the Delaunay triangulation of P, under the convex distance function defined by Q, as the points of P move along prespecified continuous trajectories. Assuming that each point of P moves along an algebraic trajectory of bounded degree, we e...
متن کاملVoronoi Diagrams and Delaunay Triangulations
The Voronoi diagram of a set of sites partitions space into regions one per site the region for a site s consists of all points closer to s than to any other site The dual of the Voronoi diagram the Delaunay triangulation is the unique triangulation so that the circumsphere of every triangle contains no sites in its interior Voronoi diagrams and Delaunay triangulations have been rediscovered or...
متن کاملHyperbolic Delaunay triangulations and Voronoi diagrams made practical
We show how to compute Delaunay triangulations and Voronoi diagrams of a set of points in hyperbolic space in a very simple way. While the algorithm follows from [7], we elaborate on arithmetic issues, observing that only rational computations are needed. This allows an exact and efficient implementation.
متن کاملAspects of Convex Geometry Polyhedra, Shellings, Voronoi Diagrams, Delaunay Triangulations
Some basic mathematical tools such as convex sets, polytopes and combinatorial topology, are used quite heavily in applied fields such as geometric modeling, meshing, computer vision, medical imaging and robotics. This report may be viewed as a tutorial and a set of notes on convex sets, polytopes, polyhedra, combinatorial topology, Voronoi Diagrams and Delaunay Triangulations. It is intended f...
متن کاملTwo-Site Voronoi Diagrams under Geometric Distance Functions
We revisit a new type of a Voronoi diagram, in which distance is measured from a point to a pair of points. We consider a few more such distance functions, and analyze the structure and complexity of the nearestand furthest-neighbor Voronoi diagrams of a point set with respect to these distance functions.
